| Abstract: | The theory of decomposing the signal with wavelet transform is introduced based on the fundamental principle of wavelet transform. Aimed at the non-stationary character of transmission gear vibration signal,Multi-Resolution Analysis is adopted to the vibration signal of transmission gear signal with the db4 wavelet.It is illustrated that the wavelet transform has get obvious effect in automobile transmission gear fault diagnosis. |
